How to change the system of CVM? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

Stop the CVM before changing the system. Changing the operating system of the CVM will directly reset the system disk. If the IP remains unchanged, the data of the system disk will be lost. Next, we describe how to change the operation of the CVM to the system.

Selection of CPU/ memory and operating system

1) if you need to select / change more than 4G memory, select a 64-bit operating system (32-bit operating system has addressing restrictions).

2) if you choose a 32-bit operating system, the memory pages above 4G will not be displayed for the time being, but only if the CVM is replaced with a 64-bit operating system.

3) the Windows 32-bit operating system supports a maximum CPU of 4 cores. Some low-configuration CVMs do not support the selection / replacement of Windows operating systems.

In addition, changing the operating system will change the system disk of the CVM to a new image, and the data of the original system disk will be lost. The data of the CVM data disk will not be affected.

It is recommended that the personal data of the system disk be backed up to the data disk, or by other means. Generally, the service provider will not be held responsible for the loss caused by the user's failure to back up the data related to the system disk. The replacement of Windows operating system is not supported for some low-memory CVM rentals.

At present, most service providers support the operation of replacing the system in the CVM management interface.
